[pass] [PATCH] Fuzzy lookup for "show" command

[Michael Traxler]

Hi Matthias,

I also agree that this feature (nested structure) is very much needed in pass,
as I always have to first use
$ pass find xyz
to find the entry and
$ pass show full-path
to display it.

And fzf on the other side is the best and most useful extension to my shell
(zsh) for a long time, even though I thought zsh is perfect :-)
So, combining the two would be perfect.

But how do I integrate it in "pass"? Can you be more specific how to do this?
"like so: ...." is too hard for me :-)

Thanks,

Michael

Hi,

please do not apply this patch.

This very behaviour can be replicated using a fuzzy-completion tools
like fzf[0], like so:

    fuzzpass() {
        local path=$(find ~/.password-store/ -name "*.gpg"  | \
            sed -r 's,(.*)\.password-store/(.*)\.gpg,\2,'   | \
            fzf +m);
        [[ ! -z "$path" ]] && pass -c $path
    }

And fzf is really damn fast and really stable (I'm using it for years
now). I think such functionality shouldn't be integrated in pass
because there are already mature tools around which enable one to
implement such a thing.
